I don't like any of this, but I'm not totally clear how this is substantially different from other fingerprinting technologies which I assume are used by every large tech company. Could anyone elaborate? The post isn't very clear why this is different from other data surveillance.
the difference is intent. regular fingerprinting identifies your browser for ad tracking. linkedin is scanning for 509 specific extensions including job search tools, and they sell recruiter products to your employer. that's not fingerprinting, that's workplace surveillance with extra steps.
If other people collect data like that it's probably also illegal.
